Ifstream file does not open although everything se

Question

I'm trying to write a program to parse the first and sixteenth columns of a CSV file (converted into .txt). I have the CSV ("posts.txt") document in the folder with the executable. But, whenever I try to run the executable, my program delivers that it cannot open the file (or that "!infile.is_open()"). Mind giving me some assistance? I'm running in Xcode 3.2.3 on Mac OSX 10.8.3. The code is shows below.

#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string.h>

using namespace std;

void answeredPostGrabber()
{
    ifstream inFile("posts.txt");

    string postNumber;
    string answerNumber;
    string throwAway;

    if(inFile.is_open())
    {

        while(inFile.good())
        {
            getline(inFile,postNumber,',');
            cout << postNumber << ",";

            for(int y=1;y++;y<16)
            {
                getline(inFile,throwAway,',');
            }
            getline(inFile,answerNumber,',');
            cout << answerNumber << endl;

            ofstream edges;
            edges.open("edges.txt",ios::app);
            edges << postNumber << "," << answerNumber<< endl;
            edges.close();

            ofstream nodes;
            nodes.open("nodes.txt",ios::app);
            nodes << postNumber << "\n" << answerNumber << endl;
            nodes.close();

            getline(inFile,throwAway);
          }
   }else cout << "ERROR: Unable to open file." << endl;
}

int main ()
{
    answeredPostGrabber();
    return 0;
}

Thank you in advance!

I have the CSV ("posts.txt") document in the folder with the executable.

The file should be present in the current working directory of your process, which may or may not be the same directory where the executable lives. If in doubt, try specifying the full path in ifstream inFile(...); to see whether that changes things.

Additionally, the file needs to have the correct permissions to ensure that it's readable by the process.
